46    
47    Version 4.3.0 (9 May 2021)
48    
49      * general changes:
50        - Require at least a C++11 compliant compiler.
51        - Require some UUID generating function by underlying system.
52    
53      * src/gig.cpp, src/gig.h:
54        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
55          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
56          allow to define override LFOs' wave form (e.g. saw or square instead of
57          the default wave form which was always sine in the original
58          Gigasampler/GigaStudio software).
59        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
60          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
61          move the start point horizontally of the LFOs' waves (0° ... 360°).
62        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
63          (the original Gigasampler/GigaStudio software only had that flip phase
64          option for LFO1 and LFO2).
65        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
66          Region::UsesAnyGigFormatExtension(),
67          Instrument::UsesAnyGigFormatExtension() and
68          File::UsesAnyGigFormatExtension() (however only as private methods yet,
69          see comments on methods why).
70        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
71          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
72          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
73          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
74          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
75        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
76          (patch by Ivan Maguidhir).
77        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
78          (original patch by Ivan Maguidhir).
79        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
80          dimensions being in different order after deleting a dimension zone.
81        - Script: Generate a persistent UUID for each script.
82        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
83          accordingly added new methods to Instrument class:
84          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
85          GetScriptPatchVariable(), SetScriptPatchVariable(),
86          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
87          as child of our '3LS ' list chunk on Instrument level.
88        - Fixed undefined behaviour when modifying script slots on an instrument
89          that had been cloned and not been saved yet (e.g. unintended modification
90          of original instrument's script slots, and crash on Instrument destruction
91          due to double free of pScriptRefs).
92    
93      * src/Serialization.cpp, src/Serialization.h:
94        - Fixed broken Archive(RawData) constructor which always threw an
95          Exception.
96        - Added built-in support for C++ String objects (a.k.a. std::string
97          from the STL) and bumped Srx format version to 1.1 for that reason.
98        - Fixed assertion fault on some systems if a member variable defined was
99          serialized which was declared as size_t or ssize_t data type.
100        - Added new method Archive::operation() which allows applications to
101          distinguish between serialization vs. deserialization in their
102          serialize() method implementations.
103        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
104          the STL).
105        - Member offsets are now signed and for (newly added support of) member
106          variables on the heap -1 is always used as offset instead.
107        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
108          STL).
109        - DataType: Added optional 2nd custom type name.
110        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
111          STL).
112    
113      * src/helper.h:
114        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
115          function call.
116    
117      * src/tools/gigdump.cpp:
118        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
119          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
120          LFO2FlipPhase and LFO3FlipPhase.
121    
122    Version 4.2.0 (25 Jul 2019)
123    
124      * general changes:
125        - Added MSVC build support (anonymous patch from mailing list).
126        - Introduced CMake build support (yet constrained for building with MSVC)
127          (anonymous patch from mailing list).
128        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
129          destructors. Added new virtual method DeleteChunks() to those classes
130          for this which must be explicitly called instead to remove their RIFF
131          chunks.
132        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
133          of zero; which is unsafe per se.
134        - Added C++11 "override" keyword where appropriate.
135        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
136          of their actions when not passing a progress_t callback structure.
137    
138      * src/gig.cpp, src/gig.h:
139        - Fixed Doxygen API comments for enum types (currently latest Doxygen
140          [v1.8.13] only supports C comments in macro arguments expansion, but
141          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
142          the Doxygen source code, which currently also filter out new line
143          \n chars).
144        - Added new method File::CountSamples().
145        - Added new method File::CountInstruments().
146        - Fixed gig v4 files falsely being handled as v2 format
147          (patch by Ivan Maguidhir).
148        - Added gig v4 version identifier (File::VERSION_4).
149        - GIG FORMAT EXTENSION: Added attribute
150          DimensionRegion::SustainReleaseTrigger which allows to define whether
151          a sustain pedal up event shall cause a release trigger sample to be
152          played (default: don't play release trigger sample by sustain pedal).
153        - GIG FORMAT EXTENSION: Added attribute
154          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
155          regular behaviour of playing release trigger sample on MIDI note-off
156          events.
157        - Introduced support for writing extension files (.gx01, .gx02, ...)
158          (original patch by Ivan Maguidhir).
159        - Many gig classes derive now from DLS::Storage (see DLS changes below).
160        - Added File::GetRiffFile() method.
161    
162      * src/DLS.cpp, src/DLS.h:
163        - File: Fixed implicitly allocated RIFF::File object never been freed.
164        - Added new abstract interface base class DLS::Storage which is derived by
165          the respective classes for implementing (the old) UpdateChunks() and the
166          new DeleteChunks() method.
167        - Added File::GetRiffFile() method.
168    
169      * src/sf2.cpp, src/sf2.h:
170        - Added Sample::GetFile() method.
171        - Added File::GetRiffFile() method.
172    
173      * src/Serialization.cpp, src/Serialization.h:
174        - Hide pure internal declarations from header file to avoid numerous
175          compiler warnings when building and linking against the public API.
176        - Fixed comparision logic bug
177        - Fixed memory leak in DataType::customTypeName().
178    
179      * src/RIFF.cpp, src/RIFF.h:
180        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
181          caused a resource leak
182        - Avoid compiler warning when building for 32 bit windows.
183        - Added new method progress_t::subdivide().
184        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
185        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
186          allows a more fine graded control into which portions the subtasks are
187          divided to.
188    
189      * src/tools/gigdump.cpp:
190        - Added command line option --instrument-names which causes only
191          instrument names and their index numbers to be printed.
192    
193    Version 4.1.0 (25 Nov 2017)
194      * general changes:
195        - removed 2 GB limitation when loading a gig or DLS file
196        - using now native integer size where appropriate
197        - fixed minor issues with man pages (patch by Debian maintainer)
198        - fixed various spelling mistakes (patch by Debian maintainer)
199        - Added new "Serialization" framework (and equally named namespace)
200          which allows to serialize and deserialize native C++ objects
201          in a portable, easy and flexible way.
202        - print compiler warning if no RTTI available
203        - Fixed potential crash in command line tools gig2stereo, korg2gig,
204          korgdump and sf2extract.
205        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
206          (original patch by Paul Brossier, slightly modified).
207        - Debian: Fixed packaging error about invalid substitution variable
208          "Source-Version".
209        - Raised Debian compatibility level to Debian 9 "Stretch".
210    
211      * src/gig.cpp, src/gig.h:
212        - fixed bug in Script::SetGroup: the script chunk wasn't moved
213        - fixed compilation error with clang 3.4
214        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
215          as one single monolithic gig file. In case .gig file is >= 2GB expect a
216          large monolithic file, otherwise if .gig file is < 2 GB check for
217          "extension" files (.gx01, .gx02, ...) instead.
218        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
219          if there were dimensions after the velocity dimension: it only created
220          valid velocity tables for cases of dimensions lower than the velocity
221          dimension.
222        - added new method Sample::VerifyWaveData() which allows to check whether
223          a sample had been damaged for some reason
224        - Fix: samples' CRC checksums were damaged on file structure changes.
225        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
226        - Added new method Sample::GetWaveDataCRC32Checksum().
227        - Changed default value of EG2Release (filter release time) to 60s.
228        - Instruments' default pitch bend range is now +-2 semi tones.
229        - Fixed CRC checksums being wrong sometimes.
230        - Fix: method File::AddContentOf() did not clone script groups and scripts
231          of passed original file.
232        - Added support for serializing & deserializing DimensionRegion
233          objects (and crossfade_t and leverage_ctrl_t objects).
234        - Added enum reflection API functions for retrieving enum declaration type
235          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
236        - Exception class now has a variadic constructor which allows to add
237          textual format specifiers like with printf().
238        - On unknown leverage controller exception: show precise unknown leverage
239          controller number found.
240        - Ignore invalid leverage controller types and just show a warning on the
241          console instead of throwing an exception.
242        - Added new struct eg_opt_t and new class member variable
243          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
244          extension to the gig file format, which allows to override the default
245          behavior of the first two EGs' state machines.
246        - Fixed undefined behavior when loading a gig file with invalid
247          velocity curve parameters (fixes CVE-2017-12951).
248        - Fixed undefined behavior when loading a gig file with invalid wave
249          pool index number (fixes CVE-2017-12954).
250    
251      * src/DLS.cpp, src/DLS.h:
252        - Sample: wave pool offsets are now 64 bits (to allow support for files
253          larger than 4 GB).
254        - Exception class now has a variadic constructor which allows to add
255          textual format specifiers like with printf().
256    
257      * src/RIFF.cpp, src/RIFF.h:
258        - added support for RIFF files larger than 4 GB, by default the required
259          internal RIFF file offset size is automatically detected (that is RIFF
260          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
261          automatically use 64 bit offsets), a particular offset size can be forced
262          with a new option added to the RIFF File constructor though
263        - when saving a modified, grown RIFF file, the temporary file size during
264          Save() operation will no longer be larger than the final grown file size
265        - Exception class now has a variadic constructor which allows to add
266          textual format specifiers like with printf().
267    
268      * src/Serialization.cpp, src/Serialization.h:
269        - Archive: Added method isModified().
270        - Archive: Added method setAutoValue().
271        - Archive: Added method setIntValue().
272        - Archive: Added method setRealValue().
273        - Archive: Added method setBoolValue().
274        - Archive: Added method setEnumValue().
275        - Archive: Added method valueAsString().
276        - Archive::rawData(): Automatically re-encode new raw data stream if
277          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
278        - Object: Added method memberByUID().
279        - Object: remove() method is now protected.
280        - Archive: Added method removeMember().
281        - Archive: Added methods name() and setName().
282        - Archive: Added methods comment() and setComment().
283        - Archive: Added methods timeStampCreated(), timeStampModified(),
284          dateTimeCreated() and dateTimeModified().
285        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
286        - DataType: Implemented demangling C++ type names (for methods
287          asLongDescr() and customTypeName(bool demangle=false)).
288        - Archive::setAutoValue(): Handle human readable boolean text
289          representations like "yes", "no", "true", "false" as expected.
290        - Exception class now has a variadic constructor which allows to add
291          textual format specifiers like with printf().
292        - DataType fix: Retain backward compatibility to older versions of native
293          C++ classes/structs.
294    
295      * src/Akai.cpp:
296        - Fixed compilation error with recent, more strict compilers.
297    
298      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

301    
302      * src/tools/korg2gig.cpp:
303        - fixed c++11 narrowing warnings
304        - fixed fine tuning which was not translated at all
305    
306      * src/tools/gigdump.cpp:
307        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
308          dimension regions
309        - additionally print RIFF chunk file offset and RIFF chunk size of sample
310          data
311        - added and implemented new parameter "--verify" which allows to check
312          the raw wave form data integrity of all samples
313        - added and implemented new parameter "--rebuild-checksums" which allows
314          to recalculate the CRC32 checksum of all samples' raw wave data and
315          rebuilding the gig file's global checksum table (i.e. in case the
316          file's checksum table was damaged)
317        - print samples' CRC32 checksums
318        - Print the new EG behavior options (eg_opt_t).
319    
320      * src/tools/gigextract.cpp:
321        - Fix: if sample name contains a path separator (slash or backslash) then
322          replace them by a minus sign to avoid file system issues.
323    
324      * src/tools/gig2stereo.cpp:
325        - Also merge mono sample pairs with non matching loop information if
326          argument --incompatible was given.
327    
328      * packaging changes:
329        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
330          auto detect whether it (sh/c)ould output its messages in color.
331    
332    Version 4.0.0 (14 Jul 2015)
333      * general changes:
334        - minor Makefile fix for parallel make

345        - moved source files of command line tools to new subdir src/tools
346        - libgig.so and libakai.so files are now installed under
347          $(prefix)/lib/libgig/ by default.
348        - Header files are now installed under $(prefix)/include/libgig/ by default.
349        - Fixed various packaging issues regarding installation directories
350          (fixes #218).
351        - added new command line tool "gig2stereo" (and a man page for it)

355    
356      * SoundFont file format:
357        - initial implementation
358        - changed region lookup API to avoid malloc in RT threads
359        - fixed GetEG1Sustain which didn't return correct value
360        - bugfix: GetPan always returned -1, 0 or 1
361    
362      * KORG file format:
363        - initial support for sample based instruments in KORG's file format
364          (.KMP and .KSF files)
365    
366      * AKAI file format:
367        - Added Linux/POSIX ported version of libakai. Note that libakai is released
368          under LGPL terms while libgig is released under GPL terms. To handle this
369          license difference appropriately the AKAI support part is built as
370          separate DLL (.so file).

387          wrong textual group name
388        - added new method File::AddContentOf() for merging .gig files
389        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
390          controller types (only works with LinuxSampler & gigedit, will not
391          work with Gigasampler/GigaStudio)

396        - added new method Region::DeleteDimensionZone(dimension_t, int)
397        - added new method Region::SplitDimensionZone(dimension_t, int)
398        - Fixed crash caused by Region::GetDimensionRegionByValue() that happened
399          with certain velocity split sounds under certain conditions (added bound
400          constraints to prevent that)

404        - added new method Region::SetDimensionType()
405        - Added support for custom progress notification while saving to gig file.
406        - Bugfix: Adding a new region in between two existing regions caused the
407          new one being dropped after save operation and the gig file being tainted
408          (chunks at wrong location in the RIFF tree).
409        - Added new method Instrument::MoveTo() which allows to rearrange the order
410          of instruments within the same gig file.
411    
412      * src/DLS.cpp, src/DLS.h:
413        - added new method File::GetFileName()
414        - fixed minor "memory leak on exception" bug found with cppcheck
415        - added new method File::GetExtensionFile(int index)
416        - added new method File::SetFileName() allowing to call File::Save()
417          later on without passing a file name
418        - added inline helper methods overlaps() for struct range_t
419        - Added support for custom progress notification while saving to DLS file.
420        - Bugfix: Adding a new region in between two existing regions caused the
421          new one being dropped after save operation and the gig file being tainted
422          (chunks at wrong location in the RIFF tree).
423    
424      * src/SF.cpp, src/SF.h:
425        - added new method Sample::ReadNoClear()
426    
427      * src/RIFF.cpp, src/RIFF.h:
428        - bugfix: avoid calling read() with count 0 when writing a file,
429          as this may hang on some systems
430        - fixed memory leak and memory handling errors when file loading
431          fails
432        - added new method Chunk::ReadString
433        - added new method File::SetFileName() allowing to call File::Save()
434          later on without passing a file name
435        - added new method File::IsNew()
436        - added support for loading RIFF-like files with a bit different layout
437          than "real" RIFF files (used for KORG format support)
438        - added new method Chunk::GetFile()
439        - added new method Chunk::GetLayout()
440        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
441          allows to move a subchunk within the current List, whereas the new 2nd
442          one allows to move the subchunk from the current list to another list
443        - POSIX: only assume -1 result value as error on open() calls
444        - POSIX: show operating system's error reason if opening a file failed
445        - Added support for custom progress notification while saving to RIFF file.
446        - Fixed embarrassing old bug: POSIX read() errors were never detected on
447          Chunk::Read() calls due to signment incompatible variable.
448        - Cleanup of an old DLL binary backward compatibility hack.
449    
450      * src/gigextract.cpp:
451        - export sample loop, unity note and fine tune with libsndfile
452    
453      * src/riftree.cpp:
454        - added more command line options for being able to also dump other kind
455          of file formats similar but not equal to the RIFF format
